Projeto e Construção de Linhas Aéreas MT e AT - Estabelecimento de Linhas Elétricas em Zonas com Alto Risco de Incêndios

Abstract

The current dissertation, proposed by EDP-Distribuição, has as it´s one of it´s core objectives the study of a High Voltage (HV -60kV) aerial powerline project that links the substation of Alto- Monção to the substation od Casarão, both situated in Águeda (Aveiro county). In this project it´s emphasized not only the mechanical calculations but also the electric calculation using high temperature conductors nased ACCC (Aluminium-Conductor Composite Core). After the fire catastrophes that hit Portugal, during the months of June and October of 2017, there was a need to find a solution for the falling of several High Voltage aerial power line posts, leading to the inevitable power in the affected areas. This dissertation will suggest and analyze several solutions that bring reinforcement and rehabilitation of the affected powerlines and how the use of high temperature conductors can contribute to ease the consequences of these catastrophes. In such, there will be an analysis on both environmental and economic impacts of the several solutions presented using the information about the origin of the impacts mentioned and finally arriving to conclusions for their reduction and make decisions on which solution to implement after their comparison.
